Hey guys, thanks so much for all the input, you wouldn't imagine how helpful it is!
I decided to redo my Komarov painting. I put a lot more focus into everything. I made sure I nailed the drawing before I did anything else. With the colors I took Umbravita's advice and just really tried to see the colors. MBK's link was also REALLY helpful. I realized there were a lot more red and peach hues than I imagined. I also did away with opacity, I think the blurryness of my work was leading to some of my confusion. The painting is still a WIP but I've gotten it to a decent point by now.
Again, thanks so much for the advice you guys!
